An important factor in the development of diabetes and its associated consequences is prolonged chronic hyperglycemia, which weakens the antioxidant defense system and produces reactive oxygen species. Phytochemicals have been found to scavenge free radicals and exhibit antioxidant effects necessary to increase insulin sensitivity and reduce the development of diabetes-related complications. Current treatments for managing diabetes and diabetic nephropathy are often not very effective and come with several limitations and side effects.

Background: The Saudi Food and Drug Authority (SFDA) has approved the subcutaneous (SC) administration of infliximab, presenting a more convenient alternative with reduced outpatient visits and diminished expenses compared to the intravenous (IV) administration. However, the financial implications of this formulation have not been examined from the perspective of Saudi payers.

Methods And Materials: A prevalence-based budget impact model was developed to evaluate the financial effects of introducing "environment without" versus "with infliximab SC.

Background: Liraglutide, a long-acting glucagon-like peptide-1 receptor agonist (GLP1RA), is a well-established anti-diabetic drug, has also been approved for the treatment of obesity at a dose of 3 mg. There are a limited number of studies in the literature that have looked at changes in metabolite levels before and after liraglutide treatment in patients with obesity. To this end, in the present study we aimed to explore the changes in the plasma metabolomic profile, using liquid chromatography-high resolution mass spectrometry (LC-HRMS) in patients with obesity.

Article Synopsis
  • The study explored the effects of the GLP-1 receptor agonist liraglutide on plasma protein profiles in patients with obesity, finding significant changes in weight, BMI, and HbA1c after three months of treatment.
  • A total of 151 proteins showed significant dysregulation, with 31 being upregulated and 120 downregulated post-treatment, highlighting potential biomarkers like Cystatin-B and multimerin-2.
  • Pathway analysis revealed major signaling pathways involved, particularly MAPK, AKT, and PKc, which play a crucial role in cell communication and could inform future obesity treatments.

Since the development of CBCT has been utilized in dentistry, the images of the CBCT can assist the surgeon to evaluate the anatomy carefully. Despite the value of radiology evaluation, implant procedures may require additional consideration rather than only evaluating the anatomical factors. The purpose of this study is to evaluate the predictability of using CBCT alone to plan for implant placement in edentulous patients digitally.
